Abstract
A method for producing a fluffy temperature regulating warmth retention material and the fluffy temperature regulating warmth retention material produced therefrom are disclosed. The method comprises: selecting a low melting point fiber and an additional fiber; carding to form a single web; spray coating a phase change material along at least part of the length of a surface of the single web; lapping layer by layer of the single web; and performing a heat setting reinforcement to form the warmth retention material. According to the present invention, a fluffy temperature regulating warmth retention material comprising an appropriate ratio of a phase change material may be obtained and the material exhibits a satisfactory temperature regulating effect, and meanwhile, it can maintain, to the full extent, or is close to, the original filling power and soft hand feeling where no phase change material is incorporated. In addition, the phase change material can be retained very well within the fluffy temperature regulating warmth retention material and thus has a wash resistance property.
